Sources of Air Pollution in Your Home

There could be a problem with the air you’re breathing. With airtight construction prodded by energy-efficient building practices over the last few decades, homes are less likely to exchange air as quickly – meaning the natural ventilation from times of old now no longer allows for the routine exchange of air between inside and outside. That means what’s inside your home stays inside your home, including the pollutants that collect over time. What’s more, because Americans spend up to 90% of their time indoors, these pollutants are potentially reaching right into your family’s breathing passages.

According to the Environmental Protection Agency, there are several common pollutants found in homes these days. They include:

Combustion Pollutants – Gases or particles that come from burning materials, major residential sources of combustion pollutants improperly vented or unvented fuel-burning appliances such as space heaters, wood stoves, gas stoves, water heaters, dryers and fireplaces. Common combustion pollutants include carbon monoxide (CO) which is a colorless, odorless gas that interferes with the delivery of oxygen throughout the body. Carbon monoxide causes headaches, dizziness, weakness, nausea and even death. Additionally, nitrogen dioxide is a colorless, odorless gas that causes eye, nose and throat irritation, shortness of breath and an increased risk of respiratory infection.

Volatile Organic Compounds (VOCs) – These are chemicals found in paints and lacquers, paint strippers, cleaning supplies, varnishes and waxes, pesticides, building materials and furnishings, office equipment, moth repellents, air fresheners and dry-cleaned clothing. VOCs evaporate into the air when these products are used or sometimes even when they are stored. VOCs irritate the eyes, nose and throat, and cause headaches, nausea and damage to the liver, kidneys and central nervous system. Some of them can cause cancer.
